In the present embodiment, the transmission member 243 includes the first bevel gear 51, the upper support frame 52, the transmission rod 53, the lower support frame 54, and the fourth bevel gear 55; the transmission rod 53 extends up and down, the upper end is provided with a second bevel gear 56, and the lower end is provided with a third bevel gear 57; the upper support frame 52 is arranged on the upper part of the transmission rod 53 through an upper ring sleeve 58, and the upper ring sleeve 58 and the transmission rod 53 can rotate and cannot move; the front end of the upper support frame 52 is also provided with a support sleeve 59, and the rear end is fixedly connected with the moving plate 251; the support sleeve 59 is rotatably connected with a rotating shaft 510; the first gear 242 is sleeved on the rotating shaft 510; the first bevel gear 51 is arranged on the rotating shaft 510 and is positioned at the rear side of the first gear 242, and the first bevel gear 51 and the second bevel gear 56 are in meshing transmission; the front end of the lower support 541 is arranged at the lower part of the transmission rod 53 through a lower ring sleeve 511, the rear end is fixedly arranged at the lower part of the moving plate 251, and the lower ring sleeve 511 and the transmission rod 53 are also rotatable and immovable; the fourth helical gear 55 is disposed at the front end of the transmission shaft 27 and is in meshing transmission with the third helical gear 57. So set up, on the basis that prevents the motion interference, structural design is more reasonable, and the transmission effect is more outstanding for the rotation of fan blade 222 and transmission shaft 27 turns into the relative movement of first gear 242 and rack 241, and realizes that first gear 242 drives adsorption equipment 2's removal smoothness nature.
The working process is as follows:
when the clamping device is used for adsorbing equipment, under the state that the clamping device corresponds to the horizontal plane of the adsorption equipment, the adsorption device 2 corresponding to the horizontal plane gradually forms an adsorption sealing environment under the downward extrusion of external force equipment under the condition that the adsorption device 2 corresponding to the horizontal plane of the adsorption equipment, and at the moment, the corresponding adsorption device 2 only moves downwards to adsorb the surface of the equipment. And the suction cavity 211 is sucked through the suction telescopic pipe 26 under the action of external suction equipment, so as to form a negative pressure cavity, and the clamping and suction stability of the device is improved. When the two suction patches 212 of one suction device 2 are simultaneously sucked in a sealed manner or are simultaneously not sucked in a sealed manner, the fan blade 222 of the wind chamber 22 does not work at this time, and the transmission member 243 does not work.
When the adsorption sleeve 21 at the outermost side meets the right-angle side of the object, namely the boundary state of the horizontal plane and the vertical plane. At this time, when only one adsorption patch 212 of the adsorption device 2 at the outermost side is sealed with the surface of the equipment, in the process of pressing down the adsorption device 2, the sealed patch discharges the gas into the air chamber 22 and discharges the gas from another patch through the rotation of the fan 222. In the rotation process of the fan blade 222, the transmission shaft 27 synchronously rotates to transmit the rotation power to the first gear 242 above, specifically, through the meshing transmission of the fourth helical gear 55 and the third helical gear 57, since the third helical gear 57 and the second helical gear 56 are coaxially arranged, the second helical gear 56 drives the first helical gear 51 and the first gear 242 to rotate. The rack 241 is fixed, the gear and the transmission member 243 move to the side of the suction patch 212 which is not sealed as a whole until the two suction patches 212 are not sealed with the surface of the object, and at this time, the lower suction sleeve 21 deflects to the vertical surface under the pressing action of the external force. And then the movable deflecting structure 25 is driven to move, specifically, the adsorbing sleeve 21 rotates to drive the connecting sleeve 33 to rotate, so that the rotating component 253 moves, specifically, the connecting sleeve 33 drives the gear iv to rotate, and further drives the bevel gear ii 35 engaged with the gear iv to rotate. The bevel gear I34 and the bevel gear II 35 are coaxially arranged; further, the helical gear I34 drives the helical gear III 36 and a driven gear 37 arranged at the rear end to rotate, and the driven gear 37 is an incomplete gear. In the initial state, the driven gear 37 is not engaged with the rack 241, and in the deflected state, the driven gear 37 is engaged with the rack 241. The driving member 243 and the lower adsorption sleeve 21 are continuously driven to move under the movement of the driven gear 37 until the two adsorption patches 212 completely adsorb and seal with the vertical surface of the object, and then the adsorption operation is completed under the action of the air suction expansion pipe 26 and the external air suction equipment.
Meanwhile, by arranging the adjusting structure 4, the one-way sliding piece 43 is in spline fit with the driving shaft 31, and the one-way sliding piece 43 and the spring 42 slide relatively. Therefore, the rotating connecting sleeve 33 deflects in the deflection process and drives the driving shaft 31 to rotate, and the one-way sliding sheet 43 is in sliding fit with the spring 42 through the through hole; one-way gleitbretter 43 can follow spring 42 downstream, make one-way gleitbretter 43 move down and as fulcrum and extension spring 42's actual action length for the absorption cover 21 that takes place to deflect pulls the pulling force and reduces, the device's practicality has been improved, avoided adsorption equipment 2 to take place to slide and lead to adsorbing the inefficacy, guaranteed clamping device to the rightting and the adsorption effect that contain the right angle object side, improved the atress homogeneity of this anchor clamps, reduced the object equipment and hung rocking of moving the in-process at this anchor clamps.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
